Installation

6 3A0735N

Installation

Grounding

Pump: Connect a ground wire (Graco PN 238909) to the ground screw on the bottom cover of the air motor, under the shroud. Connect the other end of the ground wire to a true earth ground.

Air and fluid hoses: use only electrically conductive hoses with a maximum of 500 ft. (150 m) combined hose length to ensure grounding continuity. Check elec-trical resistance of hoses. If total resistance to ground exceeds 25 megohms, replace hose immediately.

Air compressors: follow manufacturer’s recommenda-tions.

Dispense valve: ground through connection to a prop-erly grounded fluid hose and pump.

Material supply container: follow local code.

Container(s) that receive material: follow local code.

Solvent pails used when flushing: follow local code. Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive sur-face, such as paper or cardboard, which interrupts grounding continuity.

To maintain grounding continuity when flushing or relieving pressure: hold metal part of the dispense valve firmly to the side of a grounded metal pail, then trigger the valve.

Mounting

Mount the pump on a surface than can support the weight of the pump and accessories, as well as the stress caused during operation. Do not use air or fluid lines to support the pump.

Setup

NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawings.

Accessories are available from Graco. Make certain all accessories are sized and pressure-rated to meet your system requirements.

FIG. 1 is only a guide for selecting and installing system components and accessories. Contact your Graco dis-tributor for assistance in designing a system to suit your particular needs.

Install a bleed-type master air valve (G) close to the pump air inlet (D), to relieve air trapped between it and the air motor.

Install an air filter/regulator (F) in the pump air line, upstream from the bleed valve, to control air inlet pres-sure and to remove harmful dirt and contaminants from your compressed air supply.

The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.

To avoid injury from a falling pump, check the torque on the lift ring (16) and nut (15) before using the lift ring to lift the pump. Torque to 30-36 ft-lb(41-49 N•m).

To avoid contaminating the fluid, pipe the exhaust air to vent outside of the fluid product area, away from people, animals, or food-handling areas.

Installation

3A0735N 7

Install a pump runaway valve (S) in the pump air line to shut off air to the air motor automatically if the pump starts to run too fast.

Install another bleed-type master air valve (G) upstream from all air line accessories and use it to isolate the accessories during cleaning and repair.

On the air drop to the dispense valve (K), install an air regulator (M) to control air pressure to the valve. Install a bleed valve (G) to use as a shutoff when servicing the dispense valve.

Connect air solenoid valves (H) to a timer control (L), and set so the dispense valve (K) will dispense at proper intervals.

Operation

Pressure Relief Procedure

1. Shut off the air supply to the pump.

2. Close the bleed-type master air valve (required in system).

3. Open the fluid ball valve and/or dispensing valve to relieve fluid pressure.

Flush Before First UseThe sanitary pump was assembled using sanitary lubri-cant on moving parts and was tested in water. Flush the pump thoroughly with an appropriate cleaning solution, and disassemble and sanitize the parts before using the pump. See Flushing Procedure, page 9. Check national, state, and local codes for specific limitations.

Adjusting the Pump Speed and PressureSet pressure regulator to 0 psi. Open the bleed-type master air valve. Adjust the pump air regulator until the pump is running smoothly.

Allow the pump to cycle slowly until all air is pushed out of the lines (the fluid will flow in a steady stream from the fluid outlet) and the pump is primed.

With the air supply turned on, the pump will start when the dispensing valve is opened and stall against pres-sure when the valve is closed. In a circulating system, the pump operates until the air supply is turned off.

If the pump accelerates quickly, or is running too fast, stop the pump immediately and check the fluid supply. If the supply is empty and air has been pumped into the lines, refill the container and prime the pump and lines with fluid. Be sure to eliminate all air from the system.

Pump ShutdownFollow the Pressure Relief Procedure, page 8. Always stop the pump at the bottom of its stroke to prevent fluid from drying on the displacement rod. (The air motor will exhaust at the bottom and top of the stroke.)

NOTICE

Do not expose the air motor to temperatures higher than 120°F (49°C) or the immersed fluid pump to tem-peratures higher than 160°F (71°C). Excessive tem-peratures may damage the pump packings and seals.

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from injection, splashing, or moving parts. Relieve pressure when you stop pumping and before cleaning, checking, or servicing equipment. NOTICE

Never allow the pump to run dry of fluid. A dry pump will accelerate to a high speed, possibly damaging itself.

Maintenance
